Oxford High School had two former players selected in the 2015 NFL Draft in May - LSU middle linebacker

Bobby McCain
in the fifth round by the Miami Dolphins.

Alexander has been one of the best rookies in the NFL this season, while McCain made the second start of his NFL career on Sunday. But it will be McCain who'll get the playing time in the final quarter of the 2015 regular season.

Alexander has dropped his appeal of a
four-game NFL suspension
for violating the league's policy on performance-enhancing drugs. He'll miss the rest of the regular season. After his showing on Sunday, it appears McCain is going to stay in Miami's starting lineup.

The Dolphins picked McCain with an eye toward using him as a slot cornerback or nickelback as a rookie. But he started as an outside cornerback in Miami's 15-13 victory over the Baltimore Ravens on Sunday.

"What you see is a guy who is continually competing," Miami coach
Dan Campbell said
of McCain. "He didn't get frustrated by it. It didn't bother him. He gave up a few throws, but he did rally. There again, he's another young guy that the game is not too big for, and I expect him to get even better from that."

McCain did get burned for a 52-yard touchdown by Baltimore wide receiver Daniel Brown. The play came back, though, because Brown got called for offensive pass interference, a penalty that left the Ravens steaming.

"I think (the official) got it backwards," Baltimore coach
John Harbaugh said
. "I've been told by everybody that (McCain) pushed off and fell down and Dan Brown didn't push off at all. So he must have just got it backwards."

McCain said the call was correct.

"He's a bigger guy, and I tried to turn into him and go find the ball,"
McCain said
. "As I tried to find the ball, he kind of pushed me in the back."

McCain finished the game with seven tackles and broke up a pass as Baltimore quarterback Matt Schaub tried to pick on the rookie with three-time Pro Bowler Brent Grimes at the other corner for the Dolphins.

"Certainly Schaub went after him a little bit,"
Campbell said
. "But I'll say it again: All he's doing is getting game experience, and he's going to be better for it. He competed."

McCain made his first NFL start when Grimes missed the Nov. 15 game against the Philadelphia Eagles. In the two games between the 20-19 loss to the Eagles and the two-point win over the Ravens, McCain didn't play much and didn't record a tackle in either game.

McCain said he tried to stay ready for his next chance.

"Go out and do what you've been doing,"
McCain said
. "I've played nickel in four, five games. I have played corner in a couple of games. It's going out and doing what you do week in and week out in practice and making plays when they come to you."

The Dolphins think McCain has a future in the NFL.

"He's got all the physical traits, obviously, or we wouldn't be having this discussion," Miami defensive coordinator
Lou Anarumo said
. "The intangible things of competitiveness, ball skills and just being an overall tough guy lead you to believe that those traits can make him a good player."

While McCain's playing time appears to be expanding, that of his former Oxford High School teammate Alexander is over for this season, unless Tampa Bay makes the playoffs.

After making 10 tackles, including a sack, breaking up a pass and causing a fumble in the Bucs' 23-19 victory over the Atlanta Falcons on Sunday, Alexander will start serving his four-game suspension for violating the NFL policy on performance-enhancing drugs.

Alexander said the positive test came from an ingredient in an "energy drink," and he blamed himself for not checking with team personnel.

"It's my fault,"
Alexander said
. "I've never been in any trouble or anything. It's very disappointing. I'm really disappointed in myself. All they kept saying is if you're about to drink something, ask somebody first. I'm very disappointed in myself, and I hold myself accountable."

Alexander ranks second on the team with 93 tackles. He has three sacks, two interceptions and two fumble recoveries and earned the
NFC Defensive Player of the Week Award
for his performance in the Bucs' 23-20 victory over Atlanta on Nov. 1.

After winning two games last season, Tampa Bay is 6-6 and one game out of a playoff spot with four games to play in 2015. The Bucs host the New Orleans Saints on Sunday.
